What 8/13 means
With fractional odds, the first number is what you win and the second is what you stake. At 8/13, you stake £13 to win £8, so your profit is smaller than your stake. That's what makes it odds-on: the bookmaker rates this outcome as more likely to happen than not.
It's read as "eight to thirteen", but bookmakers often turn odds-on prices round, so you'll also hear 8/13 called "thirteen to eight on" or "13/8 on". Both mean the same thing.

How likely is 8/13 to win?
8/13 implies a 61.9% chance, or about 6 in 10. The bookmaker expects this outcome more often than not. The true chance is usually a little lower than this, because bookmakers build a margin into every price.
8/13 each way
An each way bet splits your stake between a win bet and a place bet, with the place part paid at a fraction of 8/13. For a £5 each way bet (£10 in total):
| Place terms | Place odds | Returns if it wins | Returns if it places |
|---|---|---|---|
| 1/4 odds | 2/13 | £13.85 | £5.77 |
| 1/5 odds | 8/65 | £13.69 | £5.62 |
At 1/5 terms, a placed finish returns £5.62 from the £10 total stake, so it still loses £4.38 overall. Each way needs bigger prices than 8/13 for the place part to cover the bet. Work out any each way bet.
If a horse at 8/13 is withdrawn
When a horse priced at 8/13 is withdrawn after you've bet on another runner in the same race, Rule 4 takes 60p from every £1 of your winnings. It applies to bets struck at a fixed price before the withdrawal. Work out a Rule 4 deduction.
